Floating Offshore Wind has the potential to provide an effective solution for the increasing energydemand of coastal communities around the world if the specific risks associated with this noveltechnology are understood and evaluated. In this paper an enhanced risk matrix methodology wasdeveloped for the risk assessment of a generic FOWT through the introduction of a third riskparameter namely the ‘technology category’. The final risk score is calculated using the average valueof all contributing parameters: consequence, likelihood and ‘technology category’ for the avoidanceof identical risk values. Individual data collection will eliminate the biases associated with theconventional risk assessment process. The critical failure causes/hazards and failure modes, rankedbased on the obtained risk scores, indicate the Floater Unit as the most hazardous of the supportingsub-structures with corrosion as its dominant failure cause. The proposed methodology validation isascertained through the comparison of obtained results with two similar studies. Its flexibility of useand implementation, combined with its familiar background, facilitate the application of the proposedmethod for a technological risk assessment of any young sector.
